拿 3.8 的 virtualenvwrapper 创建 2 的 env...
建议换个版本试试（指 python2 的

[SimWit]

@nznd 谢谢。问题好像不在于此。通过查找 2.7 的问题在于字符集的问题。解决办法来自：“https://www.cnblogs.com/ingd/p/6185347.html”。
2.5 的话，根据官网，对于 virtualenvwrapper 测试范围为 2.6~3.6 没有问题，所以很有可能是不支持创建 2.5 版本的虚拟环境。但是我使用的是 virtualenvwrapper-win 好像有些不一样。
而针对版本来说，我使用 python2.7.17,安装 virtualenvwrapper,创建 2.5 的环境，仍报相同的错误。

这个工具我之前也遇到过类似的问题,后来建环境直接使用`python -m`也挺方便

[dxySheldon]

要不试试 anaconda 创建虚拟环境

[mailmac]

python -m venv .
解君愁！！ 早都不用 virtual 了。

[SimWit]

谢谢，我之前不知道 venv，让我了解一下
